Newton's Third Law of Motion and Its Applications

For every action, there is an equal and opposite reaction.

An object in motion stays in motion unless acted upon by an external force.

Force equals mass times acceleration.

Energy cannot be created or destroyed.

Rocket propulsion

Pendulum motion

Circular motion

Thermal expansion

The fish pushes water backwards, and the water pushes the fish forward.

The fish pulls water forward, and the water pulls the fish backward.

The fish moves forward without affecting the water.

The fish and water move in the same direction.

A rocket launching into space

A bird flying upwards

The object accelerates.

The object remains at rest.

The object moves at a constant speed.
